The local functors of points of Supermanifolds
We study the local functor of points (which we call the Weil-Berezin functor)
for smooth supermanifolds, providing a characterization, representability
theorems and applications to differential calculus
Highest weight Harish-Chandra supermodules and their geometric realizations
In this paper we discuss the highest weight -finite
representations of the pair consisting of ,
a real form of a complex basic Lie superalgebra of classical type
(), and the maximal compact subalgebra of
, together with their geometric global realizations. These
representations occur, as in the ordinary setting, in the superspaces of
sections of holomorphic super vector bundles on the associated Hermitian
superspaces .Comment: This article contains of part of the material originally posted as

SUSY structures, representations and Peter-Weyl theorem for
The real compact supergroup is analized from different perspectives
and its representation theory is studied. We prove it is the only (up to
isomorphism) supergroup, which is a real form of
with reduced Lie group , and a link with SUSY structures on is established. We describe a large family of complex semisimple
representations of and we show that any -representation
whose weights are all nonzero is a direct sum of members of our family. We also
compute the matrix elements of the members of this family and we give a proof
of the Peter-Weyl theorem for
Super Distributions, Analytic and Algebraic Super Harish-Chandra pairs
The purpose of this paper is to extend the theory of Super Harish-Chandra
pairs, originally developed by Koszul for Lie supergroups, to analytic and
algebraic supergroups, in order to obtain information also about their
representations. We also define the distribution superalgebra for algebraic and
analytic supergroups and study its relation with the universal enveloping
superalgebr
Testing Cosmological General Relativity against high redshift observations
Several key relations are derived for Cosmological General Relativity which
are used in standard observational cosmology. These include the luminosity
distance, angular size, surface brightness and matter density. These relations
are used to fit type Ia supernova (SNe Ia) data, giving consistent, well
behaved fits over a broad range of redshift . The best fit to the
data for the local density parameter is .
Because is within the baryonic budget there is no need for any
dark matter to account for the SNe Ia redshift luminosity data. From this local
density it is determined that the redshift where the universe expansion
transitions from deceleration to acceleration is . Because the fitted data covers the range of the
predicted transition redshift , there is no need for any dark energy to
account for the expansion rate transition. We conclude that the expansion is
now accelerating and that the transition from a closed to an open universe
occurred about ago.Comment: Rewritten, improved and revised the discussion. This is now a
combined paper of the former version and the Addendu
HIGHEST WEIGHT HARISH-CHANDRA SUPERMODULES AND THEIR GEOMETRIC REALIZATIONS
In this paper we discuss the highest weight kr-finite representations of the pair (r, kr) consisting of r, a real form of a complex basic Lie superalgebra of classical type ( 60 A(n, n)), and the maximal compact subalgebra kr of r,0, together with their geometric global realizations. These representations occur, as in the ordinary setting, in the superspaces of sections of holomorphic super vector bundles on the associated Hermitian superspaces Gr/Kr
